Here's a great rumor. Apparently, Rohan Shravan, the Founder of Notion Ink, just let slip an interesting tidbit on their WordPress blog. He indicated that they are expecting developers will start getting Android 4.0/ICS on November 17. Of course, speculation would be that the Samsung Galaxy Nexus will probably be released around that same time. Here's a quote from the blog post,
Hello All,

Today we are doing a full system migration and platform test for our support system.

To ensure all the requests/tickets are migrated successfully to our new system, we would be offline for 4 hrs from 12:00 PM to 4:00 PM IST. Our sincere apologies for any inconvenience this may have caused.

17th is when we are expecting ICS to be finally out with the source, and then you will see whole community (aka TabletRoms) and NI pushing in ROMs with different flavors.

With Warm Regards

Rohan Shravan
It won't be long now! :D
